Re: [spring] WG Adoption Call for draft-dong-spring-sr-for-enhanced-vpn

Hi Adrian

I agree that we need an Enhanced VPN Framework architecture draft that ties
in all related drafts as well as TEAS network slicing framework and
definition.

As Jie mentioned that Enhanced VPN involved data plane provisioning of
resources and that is what the resource SIDs provides in the context of the
main use case of 5G RAN xHaul network slicing.  This is completely
orthogonal to RSVP which is stateful control plane model.

The resource SID draft I believe may need to add some more verbiage
describing in details what resources are being allocated and how this new
resource sid different from a standard prefix or adjacent sid as they both
provide SR-TE steering mechanics.

Kind Regards

Gyan
